- the information generated at each process is dealt with by filling in a slip or inputting it to a database terminal.
- IC tags using FRID technology that can be contactlessly communicated in logistics management and inventory management have been downsized and widely used in logistics.
- manufacture of articles such as automobiles In US Pat. No. 6,099,836, the production capacity using IC tags is also proposed to be managed until disposal (see, for example, Japanese Patent Application Laid-Open No. 2002-169858).
- IC tags are capable of non-contact communication and have a large storage capacity, so advanced management is expected.
- For mechanical parts such as gears it has been proposed to manage product information by attaching an IC tag and storing an ID code and various information associated therewith (see, for example, JP-A-2002-49900). ).
- Constant velocity universal joints used in automobile drive shafts and the like are designed to have a life corresponding to that of the automobile. However, knowing what conditions were actually used at the plant would be useful for future design information.
